Question

What is blood? Explain various components of blood. Explain the importance of blood.

Answer 1

Blood is a fluid found in our bodies and those of other animals that aids in the supply of essential chemicals such as oxygen and nutrition. It aids in the delivery of substances to various body parts' cells and the collection of waste substances from cells for excretion out of the body.
Blood is generated in the bone marrow, and we can donate blood since our bodies produce it again. The human body has multiple blood groups, and only one kind of blood can be donated to someone in need. We can donate blood at a number of different blood donation centres.

Complete answer:
Blood is a reddish-colored fluid connective tissue that is salty, alkaline, or colloidal in composition. It is a bodily fluid that aids in the movement of things such as oxygen and nutrients to cells, as well as the transport of metabolic waste products away from those same cells.
Components of blood-
Plasma and blood cells or corpuscles are the two components of blood. Plasma and platelets are non-living, but RBCs and WBCs are life.
1. The first is plasma. Plasma is the blood's nonliving, liquid component. It accounts for roughly half of all blood. Plasma is responsible for transporting nutrients, hormones, and proteins to the regions of the body that require them.
2. Erythrocytes are another name for red blood cells. The nucleus and biconcave are not present in RBCs. The iron-rich red blood cells, known as haemoglobin, are responsible for the red colour of blood.
3. Leukocytes, or white blood cells, are a type of white blood cell. Because leukocytes do not contain haemoglobin, they are colourless.
Importance of blood-
1. Helps in getting oxygen to each cell of the tissues.
2. Supplements such as glucose, amino acids, and unsaturated fats that are either broken down in the blood or bound to plasma proteins are provided.
3. Carbon dioxide, urea, and lactic acid, for example, are corrosive wastes that must be evacuated.
4. Immunological abilities, such as white platelet dissemination and antibody detection of distant material.
5. Changing the pH of the body.
6. Directing the body's core temperature.
7. Controlling the colloidal osmotic weight of blood is one of the water-powered capabilities.

Note:
Functions of blood are as follows-
Blood aids in the absorption of the digested portion of the meal and carries it to all of the body's cells.
It aids in the passage of oxygen from the lungs to the cells, as well as the transport of carbon dioxide produced by the cells to the lungs.
It is responsible for transporting excreta to the kidney, such as uric acid and urea.
Monocytes and neutrophils absorb dangerous bacteria and other disease-causing organisms, helping to protect humans from many diseases.
